Just a disclaimer:

Please note that nginx is reverse proxy, it's not forward proxy,
and it was never designed to be. While it could be possible to
configure nginx as a forward proxy, it's unsupported and may have
problems, including security ones.

If you already have nginx acting as a proxy for you (presumably
using proxy_pass with variables and a resolver, if /etc/hosts
doesn't work for you out of the box), an override of a particular
hostname can be easily done using an upstream{} block with a given
name.
